public class TLcdGML32Circle extends TLcdGML32Arc implements ILcd2DEditableCircleBy3Points
A Circle is an arc whose ends coincide to form a simple closed loop. The three control points shall be distinct non-co-linear points for the circle to be unambiguously defined. The arc is simply extended past the third control point until the first control point is encountered.
